Hey, thanks for subbing! I've been super busy with some general life stuff right now, but I'll try my best to finish Part 3 ASAP!

@@LuccasLab A year now and nothing since

Thank you! Now that you mention it, I have been thinking about making a blog for some time now... 🤔 My schedule is kind of tight, but I'll make it happen. Stay tuned 😉

​@@LuccasLab - Any update on that Blog idea?

Awesome, always glad to help!

No problem man! Glad you liked it

Hi there! Thanks for subscribing, means a lot to me. :-) I thought about this but turns out there's already a LOT of videos about basic electronics on UKposts. GreatScott, ElectroBOOM, Electronoobs, and Afrotechmods all make excellent videos on basic electronics components and circuit design. Also, I'd strongly recommend "The Art of Electronics" by Paul Horowitz - it's a great read and not too daunting for total beginners. As far as understanding schematics goes, there's no better way to learn than by looking them up and making your own :-) If you want to learn PCB design, the aforementioned channels cover some of that already, but maybe wait until you've mastered more basic skills. I'd recommend taking a look at SDG Electronics, Phil's Lab, EEVblog, and maybe BPS.space, too. Cheers, mate! Best of luck on your journey.

Thanks! Glad you like it.

Add in series a optocoupler for each relay coil

It's going to depend on which board you're using, as long as it has an onboard 3.3 volt regulator you should be able to use a single 18650 Li-Ion cell to power it. You could also use try using a 5 volt phone charger as well.

@@LuccasLab I'm using a Esp32 board and connecting mq135 sensor and DHT11 sensor

Thanks, glad you enjoyed the video :-)

I would like to know about hardware serial on dev module would you mind talk about on your next video?

Hey there! The next videos will focus more on IoT (getting and posting data do the internet, communications protocols, that sort of stuff), so I don't plan on covering hardware serial. Sorry about that. I found this really good video about hardware UARTs on the ESP32. You might want to check it out if you haven't already. ukposts.info/have/v-deo/nYWBdaWHbq50mHU.html&ab_channel=G6EJD-David Have a good one!

LOL! Sorry about that, I try to keep my videos as informative and straightforward as possible 😅

Can change the play speed on youtube

Try going to the UKposts Settings, change playback speed to .75 and try that!

If he slowed down people would be saying get to the point. I know how you feel but I suggest doing what I do and when you find someone like this guy watch the video several times or pause it when needed. It's better than someone dragging out an explanation when your aggravated and looking for answers
